Patent number: 10693613Abstract: A wireless telecommunications system supports a DRX operating mode for communications between a base station and terminal device, which includes a regular repeating cycle of DRX inactive periods when the terminal device monitors a downlink channel from the base station and DRX active periods when the terminal device enters a power-saving mode not monitoring the downlink channel. The terminal device transmits uplink signaling, triggering subsequent downlink signaling, that may include acknowledgement signalling for a previous downlink transmission or an uplink transmission resources request. The base station receives the uplink signalling, determines time of an upcoming DRX inactive period for the terminal device, and delays transmitting downlink signalling responding to the uplink signalling until the upcoming DRX inactive period.Type: GrantFiled: May 15, 2014Date of Patent: June 23, 2020Assignee: CONVIDA WIRELESS, LLCInventors: Jussi Kahtava, Derek John Richards

Patent number: 10645652Abstract: A communications device establishes a communications context for communicating data packets using a packet communications bearer from the communications device via the mobile communications network. A controller of the communications device is configured to identify that the communications device can enter a stasis state because no data packets are available for transmission for a predetermined time via the packet communications bearer or there are no data packets to receive via the packet communications bearer, to transmit a stasis state message to the mobile communications network, and to store information relating to the communications context associated with the packet communications bearer in a data store. The stored information can be used by the controller to re-establish the packet communications bearer to transmit and/or receive data packets using the packet communications bearer, the communications device thereby entering the stasis state.Type: GrantFiled: January 18, 2018Date of Patent: May 5, 2020Assignee: CONVIDA WIRELESS, LLCInventor: Derek John Richards

Patent number: 10531383Abstract: A communications system for communicating data to and from a communication terminal, including infrastructure equipment forming a mobile communications network arranged to transmit and receive signals representing data to and from the communication terminal via a wireless access interface. The communication terminal is configured to transmit and receive signals representing data to/from the infrastructure equipment and to enter a reduced-power state, during which the communication terminal is configured to periodically recover data from the signals received from the infrastructure equipment, to measure a parameter indicating a characteristic of at least some of the signals received from the infrastructure equipment during the reduced power state, and to exit the reduced power state and to transmit a message to the infrastructure equipment, the message requesting resources of the wireless access interface, in dependence upon the measured parameter relative to a predetermined threshold.Type: GrantFiled: August 4, 2014Date of Patent: January 7, 2020Assignee: SONY CORPORATIONInventors: Jussi Kahtava, Derek John Richards

Publication number: 20030009580Abstract: A telecommunications network comprises of network resources including at least one service domain which has a user's terminal. There is a controller operative to control transmissions of a data stream from or to the user's terminal with a predetermined quality of service. The quality of service depends on the terms of a service level agreement between the user and the service domain, processed by the controller into a set of policies to be applied. The policies include dynamic selection and allocation of the network resources so as to transmit the data stream with the expected quality of service.Type: ApplicationFiled: April 5, 2002Publication date: January 9, 2003Inventors: Xiaobao X.

Patent number: 3969778Abstract: A toilet aid is designed for use with a W.C. to assist disabled, elderly and infirm persons using the W.C. The aid is constructed for attachment to the W.C. pan using the normal seat-attachment bolt holes provided in the pan. An arm structure has side support arms which extend fowardly on either side of a user when seated on the toilet seat. The arms have inturned end portions to provide front support for the user, these portions being movable to the side to a front entry position which permits free entry and exit between the arms. When the arm portions are in this entry position the main side portions of the arms remain in their normal side support position, thus being positioned to assist the user when maneuvering into and out of the seated position. The aid can be used with all normal W.C. suites with a standard toilet seat.Type: GrantFiled: May 8, 1975Date of Patent: July 20, 1976Assignee: Mecanaids LimitedInventor: Derek John Richards
